Findings

Neck: On the lateral radiograph of the neck, the trachea is markedly narrowed. The nasopharynx is decreased in size and the soft palate appears thickened.

Thorax: There is an interstitial to alveolar pulmonary pattern in the left and right cranial lung lobes and right middle lung lobe. The cardiac silhouette is normal in size. There are multiple hemivertebrae in the spine, consistent with breed. On the d/v projections, there is an alternately fluid and gas-filled rounded structure in the caudal mediastinum. This is not visible on the lateral projections.
